[Source] Tiny gold and silver charms

Hi,

I am looking for a source of tiny gold and silver charms. While I can
find regular size charms without much trouble, I could not find a
place that sells the tiny ones I need (4-7mm). I have seen those as
parts of earrings and used components from scrap earrings before.
That worked well, but now I used all of those and can not find
anymore.

Thanks,
Birgit
